"XL's strong second quarter performance was built on a broad foundation, as all of our key value drivers contributed to an annualized operating ROE of 10.3%. Our risk management discipline has put XL's catastrophe loss experience, measured as a percentage of shareholders' equity, among the best of our peers for both the second quarter and the year to date. XL continued to pursue profitable underwriting opportunities in both existing and expanded markets, and added teams and leaders in lines we consider attractive. Our semi-annual actuarial review of XL's P&C risk portfolio, which followed our prudent reserving practices, resulted in continued favorable development. Our operating expense run-rate was in line with the last two quarters. XL's capital strength supported our underwriting expansion, strategic initiatives and the recommencing of our share buyback program, resulting in second quarter buybacks of 4.3 million shares."

Operating net income was consistent with the prior year quarter as select new business growth combined with an increase in income from operating affiliates and positive prior year loss development was largely offset by larger natural catastrophe losses and other large individual losses incurred during the current quarter.

Net investment income for the quarter was $296.5 million compared to $302.6 million in the prior year quarter and $280.3 million for the first quarter of 2011. The decline against the prior year was primarily due to lower U.S. interest rates and cash outflows from the P&C invested portfolio.

Net income from affiliates contributed $56.5 million in the quarter compared to $40.1 million in the prior year quarter as a result of strong performance primarily from investment manager affiliates.

Net realized investment losses for the quarter were $9.5 million compared to $61.4 million in the prior year quarter.

Fully diluted book value per ordinary share increased by 6.3% from the prior quarter driven primarily by earnings combined with the benefit of share buybacks and unrealized gains in investments.

During the quarter, the Company purchased 4.3 million shares for $92.3 million at an average price of $21.36, which was accretive to book value per ordinary share by $0.12. Since June 30, 2011, the Company purchased an additional 7.3 million shares for $157.7 million. $440.4 million of shares remains available for purchase under the Company’s previously announced $1 billion share buyback program.

P&C gross premiums written (“GPW”) increased 16.9% from the prior year quarter, driven by an increase in the Insurance segment of 18.8% and in the Reinsurance segment of 12.1%. Insurance segment growth in GPW included new business initiatives, primarily in North American Property and Casualty, and the impact of foreign exchange. The increase in GPW for Reinsurance was attributable to increased new business and pricing in Property Catastrophe lines, a new international casualty treaty and increased volume on a U.K. motor treaty.

P&C net premiums earned (“NPE”) of $1.3 billion was comprised of $907.4 million from the Insurance segment and $398.7 million from the Reinsurance segment. Compared to the prior year quarter, Insurance NPE increased by 4.5% and Reinsurance NPE increased by 14.7%.

The P&C loss ratio was 1.7 percentage points higher than the prior year quarter. Included in the loss ratio was favorable prior year development of $127.6 million compared to $82.3 million in the prior year quarter. The loss ratio was also impacted by natural catastrophe lossesof $68.3 million, net of reinstatement premiums. In the prior year quarter, natural catastrophe losseswere $16.8 million, net of reinstatement premiums. Excluding prior year development and natural catastrophe losses, the second quarter loss ratio was 0.7 percentage points higher than the prior year quarter primarily due to an increased number of large marine and aerospace specialty losses.

Operating expenses were largely in-line with the fourth quarter of 2010 and first quarter of 2011. Increased expenses versus the prior year quarter related largely to the build-out of the Company’s previously announced initiatives including the office of strategic growth.

The P&C combined ratio excluding prior year development and the impact of natural catastrophe lossesfor the quarter was 99.4%, compared to 97.6% for the prior year quarter. The Insurance segment combined ratio on this basis was 103.5% for the quarter compared to 99.6% for the prior year quarter, while the Reinsurance segment combined ratio on this basis was 90.0% compared to 92.7% for the prior year quarter. Combined ratios in both segments were impacted by increased acquisition expenses due to profit commissions and other adjustments.

Further details of the results for the quarter may be found in the Company’s Financial Supplement, which is dated August 2, 2011 and is available from the Investor Relations section of the XL Group website.

(1) Defined as net income (loss) attributable to ordinary shareholders excluding net realized gains and losses on investments, net realized and unrealized gains and losses on derivatives, net of tax, for the Company and its share of these items for the Company’s insurance company affiliates for the periods presented, the gains recognized on the repurchase of the Company’s preference ordinary shares, as well as foreign exchange gains or losses, net of tax. “Operating net income” and “annualized return on ordinary shareholders’ equity” based on operating net income are “non-GAAP financial measures.” The results from prior periods have been reclassified to conform to the current period presentation. See the schedule entitled “Reconciliation” at the end of this release for a reconciliation of “operating net income” to net income (loss) attributable to ordinary shareholders and of “annualized return on ordinary shareholders’ equity” based on operating net income to average ordinary shareholders’ equity.

(2) Book value per share and fully diluted book value per ordinary share are non-GAAP financial measures and represent book value per ordinary share (total shareholders’ equity less preference shareholders’ equity and non-controlling interest in equity of consolidated subsidiaries, divided by the number of outstanding ordinary shares at any period end) combined with the dilutive impact of potential future share issues at any period end. The dilutive impact of the Company’s equity security units has been included within fully diluted book value per ordinary share under the “treasury stock” method. Had this dilution been calculated under the “if-converted” method, the result would have been $30.19 per ordinary share at June 30, 2011. The Company believes that fully diluted book value per ordinary share is a financial measure important to investors and other interested parties who benefit from having a consistent basis for comparison with other companies within the industry. However, this measure may not be comparable to similarly titled measures used by companies either outside or inside of the insurance industry.

Note 1: During the first quarter of 2011, the Redeemable Series C preference ordinary shares were reclassified as Non-controlling interest – Redeemable Series C preference ordinary shares and Series E preference ordinary shares were reclassified as Non-controlling interest in equity of consolidated subsidiaries on the Company's consolidated balance sheet as a result of changes in ownership structure arising as part of the Company's redomestication of the ultimate parent holding company to Ireland as of July 1, 2010. Accordingly, preference share dividends declared are recorded as Non-controlling interests rather than as Preference share dividends within the consolidated statements of income from July 1, 2010 onwards.

Comment on Regulation G

XL presents its operations in the way it believes will be most meaningful and useful to investors, analysts, rating agencies and others who use XL’s financial information in evaluating XL’s performance. This press release contains the presentation of (i) operating net income (loss) (“Operating Net Income”), which is defined as net income (loss) attributable to ordinary shareholders excluding net realized gains and losses on investments, net realized and unrealized gains and losses on credit, structured financial and investment derivatives, net of tax, for the Company and its share of these items for the Company’s insurance company affiliates for the periods presented, the gains recognized on the repurchase of the Company’s preference ordinary shares, as well as foreign exchange gains or losses, net of tax (ii) annualized return on ordinary shareholders’ equity (“ROE”) based on operating net income (loss) (“Operating ROE”) and (iii) book value per ordinary share (ordinary shareholders’ equity divided by the number of shares outstanding at the period end date) and fully diluted book value per ordinary share (book value per share combined with the dilutive impact of potential future share issues at any period end). These items are “non-GAAP financial measures” as defined in Regulation G. The reconciliation of such measures to the most directly comparable GAAP financial measures in accordance with Regulation G is included in this press release.
Although the investment of premiums to generate income (or loss) and realized capital gains (or losses) is an integral part of XL’s operations and the Company’s insurance company operating affiliates, the determination to realize capital gains (or losses) is independent of the underwriting process. In addition, under applicable GAAP accounting requirements, losses can be created as the result of other than temporary declines in value without actual realization. In this regard, certain users of XL’s financial information, including certain rating agencies, evaluate earnings before tax and capital gains to understand the profitability of the recurring sources of income without the effects of this variable. Furthermore, these users believe that, for many companies, the timing of the realization of capital gains is largely a function of economic and interest rate conditions.
Investment derivatives include all derivatives entered into by XL other than credit derivatives. With respect to credit derivatives, because XL and its insurance company operating affiliates generally hold financial guaranty contracts written in credit default derivative form to maturity, the net effects of the changes in fair value of these credit derivatives are excluded (similar with other companies’ treatment of such contracts) as the changes in fair value each quarter are not indicative of underlying business performance.
The gains recognized on the repurchase of the Company’s preference ordinary shares are excluded as these transactions were capital in nature and outside the scope of the Company’s underlying business.
Foreign exchange gains and losses in the income statement are only one element of the overall impact of foreign exchange fluctuations on the Company’s financial position and are not representative of any economic gain or loss made by the Company. Accordingly, it is not a relevant indicator of financial performance and it is excluded.
In summary, XL evaluates the performance of and manages its business to produce an underwriting profit. In addition to presenting net income (loss), XL believes that showing operating net income (loss) enables investors and other users of XL’s financial information to analyze XL’s performance in a manner similar to how management of XL analyzes performance. In this regard, XL believes that providing only a GAAP presentation of net income (loss) makes it much more difficult for users of XL’s financial information to evaluate XL’s underlying business. Also, as stated above, XL believes that the equity analysts and certain rating agencies that follow XL (and the insurance industry as a whole) exclude these items from their analyses for the same reasons and they request that XL provide this non-GAAP financial information on a regular basis.
Operating ROE is a widely used measure of any company’s profitability that is calculated by dividing annualized Operating Net Income for any period by the average of the opening and closing ordinary shareholders’ equity. The Company establishes target Operating ROEs for its total operations, segments and lines of business. If the Company’s Operating ROE targets are not met with respect to any line of business over time, the Company seeks to re-evaluate these lines.
